| 1 | This standard specifies the factory acceptance vibration test procedure, measurement conditions and fixes the limits for the level of vibration magnitude of an electrical machine. This revision has been undertaken to bring it inline with international practices with the following significant technical changes with respect to previous version: a) Exclusion of turbine generators greater than 20 MW and machines with magnetic bearings b) Clause 4.2,4.3,5,6.2.3, 6.2.4, 6.3 are upgraded in line with IEC 60034-14:2018 c) Clause 7.2, 7.3, 8.1, 8.3, 8.4 and 9 are upgraded in line with IEC 60034-14: 2018 d) Limits of vibration magnitude defined under rigid mounting condition for frame size more than 132 e) New vibration grades A & B are defined. f) Reduction of Limits of vibration magnitude for two pole motors in frame sizes above 225 to make it in line with IEC 60034-14: 2018 g) Split of Table 2 into Table 2A and Table 2B h) Replacement of ‘vibration severity’ with term ‘vibration magni | |
